VOS3000 CDR Query Blackout Secure Deny Time Configuration

🔒 Imagine this scenario: your billing team is running the end-of-month reconciliation, processing millions of CDR records to generate invoices, when a reseller launches a massive CDR query that consumes database resources and slows the entire billing run to a crawl. The VOS3000 CDR query blackout feature, controlled by SERVER_QUERY_CDR_DENY_TIME, prevents exactly this situation by blocking CDR queries during specified hours — protecting your database during critical billing windows, maintenance periods, and peak processing times. ⏱️

📊 The VOS3000 CDR query blackout is a server-level parameter that defines specific hours of the day when CDR queries are denied to all users through the VOS3000 Client and web interface. During these blackout hours, any attempt to query CDR records returns a restriction notice instead of results. This ensures that database resources remain fully available for billing calculations, report generation, and system maintenance without interference from ad-hoc queries. 🛡️

🔐 What Is VOS3000 CDR Query Blackout?

📋 The VOS3000 CDR query blackout is a time-based access control mechanism that restricts CDR queries during designated hours. When enabled, users cannot search, view, or export CDR records through the VOS3000 Client or web portal during the configured blackout window. This protects database performance during periods when the system needs maximum resources for internal processing. 🚫

💡 Why carriers need CDR query blackout:

💰 Billing run protection: Monthly reconciliation processes millions of CDRs — concurrent user queries can cause severe performance degradation
📊 Report generation: Automated reports require exclusive database access to complete within acceptable timeframes
🔧 Maintenance windows: Database optimization, index rebuilding, and data archival should not compete with query traffic
🛡️ Data integrity: Prevents partial or inconsistent CDR views during data migration or settlement processing
📋 Regulatory compliance: Some jurisdictions require controlled access to CDR data during audit periods

⚙️ SERVER_QUERY_CDR_DENY_TIME — The Core Parameter

🔒 SERVER_QUERY_CDR_DENY_TIME defines the hours during which CDR queries are blocked. The parameter uses a 24-hour clock format, specifying which hours of the day are denied for CDR access. 📋

Attribute	Value
📌 Parameter Name	SERVER_QUERY_CDR_DENY_TIME
🔢 Default Value	None (no blackout by default)
📐 Format	Comma-separated hour values (24-hour format)
📝 Description	No CDR Query Time (24 hour) e.g. 18,19,20,21,22,23
📍 Location	Operation management → Softswitch management → Additional settings → Server parameter

🔧 Configuration format: The parameter accepts comma-separated integer values representing the hours of the day (0–23) when CDR queries are blocked. For example, to block CDR queries from 6 PM to midnight, set the value to: 18,19,20,21,22,23. Each value represents one complete hour — setting “18” blocks queries from 18:00:00 to 18:59:59.

📋 VOS3000 CDR Query Blackout Configuration Examples

📊 Here are practical examples showing how to configure the VOS3000 CDR query blackout for different operational scenarios: 💡

Scenario	Parameter Value	Blackout Window	Use Case
📞 Evening billing run	18,19,20,21,22,23	6 PM – Midnight	🔒 Monthly reconciliation during off-peak evening hours
📊 Overnight processing	0,1,2,3,4,5	Midnight – 6 AM	🔧 Database maintenance and report generation
💰 End-of-day billing	22,23,0,1	10 PM – 2 AM	📋 Daily settlement across midnight boundary
🛡️ All-day restriction	0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23	24 hours	🚨 Complete CDR access lockdown during audits
✅ No restriction	(leave empty)	None	📊 Default — CDR queries available 24/7

⚠️ Important note: The blackout hours are specified in the server’s local timezone. If your VOS3000 server is configured in UTC and your billing team works in a different timezone, you must convert the desired blackout window to match the server timezone. For example, if your billing team in Dhaka (UTC+6) wants to block queries from 6 PM to 10 PM local time, and the server is in UTC, the parameter should be set to 12,13,14,15,16 (6 PM UTC+6 = 12 UTC, 10 PM UTC+6 = 16 UTC). 🌐

📋 Step-by-Step VOS3000 CDR Query Blackout Configuration

🖥️ Follow these steps to configure the CDR query blackout on your VOS3000 system: 🔧

Step 1: Determine Blackout Window ⏱️

📊 Identify the hours when CDR queries should be blocked based on your operational needs:

📅 Billing run schedule: When does your monthly/daily reconciliation run?
🔧 Maintenance windows: When are database optimizations scheduled?
📊 Report generation: When do automated reports run?
🌍 Timezone alignment: Convert desired blackout hours to server timezone if different

Step 2: Configure the Parameter 📌

🔐 Log in to VOS3000 Client
📌 Navigate: Operation management → Softswitch management → Additional settings → Server parameter
🔍 Locate SERVER_QUERY_CDR_DENY_TIME
✏️ Enter the comma-separated hour values (e.g., 18,19,20,21,22,23)
💾 Save and apply the configuration

Step 3: Verify Blackout Enforcement ✅

🔍 After configuration, verify that the blackout is working correctly:

🕐 Wait until a configured blackout hour
📊 Attempt to query CDR records through the VOS3000 Client
✅ Confirm that the query is denied with a restriction message
🕐 After the blackout window ends, verify that CDR queries are restored

🔗 The CDR query blackout works alongside several other CDR access control parameters that together form a comprehensive data protection strategy: 📋

Parameter	Default	Purpose	Complements Blackout?
SERVER_QUERY_CDR_DENY_TIME	None	Blocks CDR queries during specified hours	🔑 Core parameter
SERVER_QUERY_CDR_MAX_DAY_INTERVAL	31	Limits CDR query date range to 31 days max	✅ Prevents heavy queries outside blackout
SERVER_QUERY_MAX_ONE_PAGE_SIZE	200000	Maximum records per page in query results	✅ Limits query result size
SERVER_QUERY_MAX_SIZE	30000000	Total data query limit (items)	✅ Prevents runaway queries
SERVER_QUERY_ONE_PAGE_SIZE	10000	Default records per page	✅ Standard pagination control

💡 Layered protection strategy: For maximum database protection, combine the VOS3000 CDR query blackout with the date range limit (SERVER_QUERY_CDR_MAX_DAY_INTERVAL) and query size limits. The blackout prevents access during critical processing hours, while the date range and size limits prevent excessively heavy queries at any time. This layered approach ensures that even when queries are permitted, they cannot consume excessive resources. For the date range limit configuration, see our CDR query date range guide. 🔗

🛡️ Common VOS3000 CDR Query Blackout Problems and Solutions

❌ Misconfigured blackout settings can cause either insufficient protection or unexpected access denial. Here are the most common issues: 🔍

❌ Problem 1: CDR Queries Still Allowed During Blackout Hours

🔍 Symptom: Users can still query CDR records during the configured blackout hours.

💡 Cause: The parameter value may contain formatting errors, or the configuration may not have been properly applied after saving.

✅ Solutions:

🔧 Verify the parameter value uses correct comma-separated format (e.g., 18,19,20 — not 18-20 or 6pm-8pm)
📊 Ensure there are no spaces in the parameter value
🔄 Re-apply the configuration and restart the softswitch service if necessary
🕐 Confirm you are testing during the correct hours based on the server timezone

❌ Problem 2: Blackout Applied in Wrong Timezone

🔍 Symptom: CDR queries are blocked at unexpected times — not during your intended window.

💡 Cause: The SERVER_QUERY_CDR_DENY_TIME operates on the server’s system clock timezone, which may differ from your local timezone. If the server is configured in UTC and you specified hours in your local timezone, the blackout window will be offset.

✅ Solutions:

🌐 Check the server timezone: date or timedatectl on the VOS3000 Linux server
🔄 Convert your desired blackout hours to the server’s timezone
📋 Update the parameter with the corrected hour values
🕐 Verify by testing a query during the intended blackout window

❌ Problem 3: Resellers Unable to Access CDRs During Business Hours

🔍 Symptom: Resellers complain they cannot check their CDRs during normal working hours.

💡 Cause: The blackout window is set too broadly, covering business hours in addition to billing run periods. This is common when operators set the blackout for the entire evening without narrowing it to the actual billing processing window.

✅ Solutions:

⏱️ Narrow the blackout window to only the hours when billing runs actually occur
📊 Schedule billing runs during the lowest-traffic period (typically late night or early morning)
📋 Communicate the blackout schedule to all resellers in advance
🔄 If resellers need CDR access, provide them with the CDR text file backup or real-time forwarding as an alternative

❌ Problem 4: Blackout Not Preventing Heavy Queries Outside Blackout Hours

🔍 Symptom: Database performance degrades from heavy CDR queries that run outside the blackout window.

💡 Cause: The VOS3000 CDR query blackout only restricts access during specified hours. Outside those hours, users can still run very large queries that impact performance.

✅ Solutions:

📅 Set SERVER_QUERY_CDR_MAX_DAY_INTERVAL to limit query date ranges (default: 31 days)
📦 Reduce SERVER_QUERY_MAX_ONE_PAGE_SIZE to limit result set sizes
📊 Monitor slow queries in the database and identify the heaviest users
📋 For more on managing query performance, see our CDR analysis guide

❓ Frequently Asked Questions

❓ What is the default value for SERVER_QUERY_CDR_DENY_TIME?

📋 The default value is None (not configured), which means there is no CDR query blackout — all users can query CDR records at any time. To enable the VOS3000 CDR query blackout, set the parameter to a comma-separated list of hours (0–23) when queries should be blocked. For example, 18,19,20,21,22,23 blocks CDR queries from 6 PM to midnight each day. 🔧

❓ Does the VOS3000 CDR query blackout apply to all users?

🔒 Yes. The SERVER_QUERY_CDR_DENY_TIME parameter applies at the server level, which means it blocks CDR queries for all users — including administrators, agents, and resellers. There is no per-user or per-role exemption. During the blackout hours, no one can query CDR records through the VOS3000 Client or web interface. If you need differentiated access control, consider using the VOS3000 Web API with custom application-level access controls. For Web API details, see our VOS3000 Web API account management guide. 🔗

❓ Can I configure different blackout windows for different days of the week?

📅 No. The VOS3000 CDR query blackout applies the same hours every day. The SERVER_QUERY_CDR_DENY_TIME parameter does not support day-of-week differentiation — if you set 18,19,20, CDR queries are blocked from 6 PM to 9 PM on Monday through Sunday. If you need different schedules for weekdays vs weekends, you would need to manually change the parameter value, or implement a custom automation script that updates the parameter on a schedule. 🔄

❓ How does the VOS3000 CDR query blackout interact with automated reports?

📊 The VOS3000 CDR query blackout restricts manual CDR queries through the client and web interfaces. Automated report generation (configured under Navigation → Report management) may operate independently of the blackout restriction since reports are generated by the system internally rather than through the query interface. However, if automated reports rely on the same query mechanism, they may also be affected. Always test your report generation schedule against the blackout window to ensure reports can complete successfully. For report configuration, see our billing system overview. 📋

❓ What happens when a user tries to query CDRs during the blackout?

🚫 When a user attempts to search or view CDR records during the configured blackout hours, the VOS3000 system denies the query and displays a restriction notice. The user is informed that CDR queries are not available during this time period. No partial results are returned. The query does not execute at all — it is blocked before reaching the database, ensuring zero impact on database performance during the blackout window. 🔒

❓ Can I temporarily disable the blackout for emergency CDR access?

🔧 Yes. To temporarily disable the VOS3000 CDR query blackout, set the SERVER_QUERY_CDR_DENY_TIME parameter to empty (None) and save the configuration. This immediately restores CDR query access for all users. After the emergency access is no longer needed, re-enter the blackout hours and save again. Remember to re-enable the blackout promptly to maintain database protection during billing runs. For help managing VOS3000 parameters, contact our team at WhatsApp: +8801911119966. 💬

VOS3000 Fee Decimal Precision Accurate Rate Unit Configuration

April 19, 2026April 19, 2026 king

VOS3000 Fee Decimal Precision Accurate Rate Unit Configuration

Configuring VOS3000 fee decimal precision correctly is critical for wholesale VoIP carriers who process millions of calls daily. The SERVER_BILLING_FEE_PRECISTION and SERVER_BILLING_FEE_UNIT parameters control how many decimal places your billing rates support and the minimum rounding unit applied to every fee calculation. Need help with precision settings? Contact us on WhatsApp: +8801911119966 for expert VOS3000 configuration support.

Even a fraction of a cent per call compounds into significant revenue differences over high-volume traffic. Setting VOS3000 fee decimal precision to 3 or 4 decimal places ensures your billing engine captures every fraction of revenue, while the FEE_UNIT parameter determines the smallest granularity at which fees are rounded. Together, these two parameters define the mathematical accuracy of your entire billing system.

Understanding SERVER_BILLING_FEE_PRECISTION in VOS3000

The SERVER_BILLING_FEE_PRECISTION parameter (documented in §4.3.5.1) controls the number of decimal places used when storing and calculating billing rates in VOS3000. Valid values range from 0 to 4, where 0 means whole numbers only and 4 provides precision to 0.0001. For wholesale carriers operating on thin margins, even the difference between 2 and 3 decimal places can impact profitability at scale.

📋 Parameter	📋 Value
Parameter Name	SERVER_BILLING_FEE_PRECISTION
Manual Section	§4.3.5.1
Data Type	Integer (0–4)
Default Value	2 (two decimal places)
Scope	System-wide (all rate calculations)
Effect	Controls decimal digits in billing rates

VOS3000 Fee Decimal Precision Values Explained

Each VOS3000 fee decimal precision level serves different business models. Retail providers typically use 2 decimal places ($0.01), while wholesale carriers operating on margins of $0.001 per minute or less require 3 or 4 decimal places to maintain accurate billing. The table below shows how each precision level affects rate representation.

📋 Precision Value	📋 Smallest Unit	📋 Rate Example	📋 Best For
0	$1	$5	Flat-rate services only
1	$0.1	$0.5	Bulk toll-free services
2	$0.01	$0.05	Retail VoIP providers
3	$0.001	$0.005	Wholesale carriers (recommended)
4	$0.0001	$0.0045	Ultra-thin margin wholesale

Understanding SERVER_BILLING_FEE_UNIT in VOS3000

The SERVER_BILLING_FEE_UNIT parameter works alongside VOS3000 fee decimal precision to define the minimum rounding unit for fee calculations. While FEE_PRECISTION controls how many decimal places are stored, FEE_UNIT determines the smallest increment at which fees are rounded after calculation. This parameter ensures that billing results conform to a practical monetary unit.

📋 Parameter	📋 Value
Parameter Name	SERVER_BILLING_FEE_UNIT
Manual Section	§4.3.5.1
Data Type	Decimal
Default Value	0.01 (one cent)
Scope	System-wide (all fee rounding)
Effect	Sets minimum rounding increment for fees

How FEE_UNIT and VOS3000 Fee Decimal Precision Work Together

The interaction between FEE_PRECISTION and FEE_UNIT is where the real billing accuracy is determined. FEE_PRECISTION defines the storage format, while FEE_UNIT defines the rounding boundary. For example, with FEE_PRECISTION=3 and FEE_UNIT=0.001, a calculated fee of $0.00456 is stored with 3 decimal places but rounded to the nearest $0.001, resulting in $0.005. Understanding this interplay is essential for VOS3000 billing precision configuration.

📋 Raw Fee	📋 Precision=2, Unit=0.01	📋 Precision=3, Unit=0.001	📋 Precision=4, Unit=0.0001
$0.00456	$0.01	$0.005	$0.0046
$0.02341	$0.02	$0.023	$0.0234
$0.15678	$0.16	$0.157	$0.1568
$1.23456	$1.23	$1.235	$1.2346

For tailored advice on which precision and unit settings fit your traffic profile, reach out on WhatsApp: +8801911119966.

Why 0.001 Precision Matters for Wholesale Carriers

In wholesale VoIP, margins are measured in thousandths of a dollar per minute. A rate of $0.005 per minute with 2-decimal precision would be stored as $0.01 — a 100% markup over the intended rate. With VOS3000 fee decimal precision set to 3, the rate is stored as $0.005, accurately reflecting the agreed price. Over 10 million minutes per month, the difference between $0.005 and $0.01 per minute equals $50,000 in billing discrepancy.

📋 Monthly Volume	📋 Precision=2 Revenue	📋 Precision=3 Revenue	📋 Difference
1 million minutes	$10,000 ($0.01/min)	$5,000 ($0.005/min)	$5,000
5 million minutes	$50,000	$25,000	$25,000
10 million minutes	$100,000	$50,000	$50,000
50 million minutes	$500,000	$250,000	$250,000

Configuring VOS3000 Fee Decimal Precision Step by Step

Setting up VOS3000 fee decimal precision and fee unit requires careful planning. Changing these parameters on a live system affects all future billing calculations and may cause discrepancies with existing CDR records. Always back up your database before modifying precision settings, as recommended in our VOS3000 MySQL backup guide.

📋 Step	📋 Action	📋 Details
1	Backup VOS3000 database	Full MySQL dump before any changes
2	Navigate to System Settings	Go to Billing Parameters section
3	Set SERVER_BILLING_FEE_PRECISTION	Enter 3 for wholesale, 2 for retail
4	Set SERVER_BILLING_FEE_UNIT	Enter 0.001 for wholesale, 0.01 for retail
5	Save and restart billing service	Apply changes and restart the engine
6	Verify with test CDR calculation	Confirm rates display correct decimal places

Rounding Mode Effects on Cumulative Revenue

The rounding behavior driven by VOS3000 fee decimal precision and FEE_UNIT has a compounding effect on revenue. When fees are rounded up at the unit boundary, each individual rounding adds a tiny surplus, but across millions of calls, this surplus accumulates significantly. Conversely, rounding down reduces revenue per call. Understanding whether your VOS3000 system rounds up, down, or to the nearest value is essential for financial reconciliation.

📋 Calls per Month	📋 Avg Rounding per Call	📋 Monthly Rounding Impact
100,000	$0.0005	$50
1,000,000	$0.0005	$500
10,000,000	$0.0005	$5,000
100,000,000	$0.0005	$50,000

Frequently Asked Questions About VOS3000 Fee Decimal Precision

What is SERVER_BILLING_FEE_PRECISTION in VOS3000?

SERVER_BILLING_FEE_PRECISTION is a system-wide billing parameter in VOS3000 that controls the number of decimal places used when storing and calculating billing rates. The valid range is 0 to 4, where 0 means whole-number rates only and 4 provides precision down to 0.0001. The default value of 2 supports rates to the nearest cent ($0.01), which is sufficient for retail VoIP but inadequate for wholesale carriers who need rate granularity at the $0.001 level or finer to accurately represent thin-margin pricing agreements.

What is SERVER_BILLING_FEE_UNIT in VOS3000?

SERVER_BILLING_FEE_UNIT defines the minimum rounding unit applied to fee calculations in VOS3000 after the billing engine computes the raw charge. While FEE_PRECISTION determines how many decimal places are stored, FEE_UNIT determines the smallest increment to which fees are rounded. For example, with FEE_UNIT set to 0.001, a calculated fee of $0.00456 rounds to $0.005. The default value is 0.01 (one cent), which works for retail billing but must be reduced to 0.001 for accurate wholesale rate processing.

Why does VOS3000 spell PRECISTION instead of PRECISION?

The parameter name SERVER_BILLING_FEE_PRECISTION uses a non-standard spelling of “precision” that appears in the official VOS3000 documentation under §4.3.5.1. This is simply the naming convention used by the VOS3000 development team and must be used exactly as spelled when configuring the system. Using the standard English spelling “PRECISION” will not be recognized by the VOS3000 billing engine. Always reference the official parameter names from the VOS3000 documentation when making configuration changes.

Can I change VOS3000 fee decimal precision on a running system?

Technically, you can modify SERVER_BILLING_FEE_PRECISTION on a running VOS3000 system, but it is strongly recommended to schedule changes during a maintenance window. Changing precision affects how existing rates are displayed and how new billing calculations are performed. Existing CDR records retain their original precision, which can create reconciliation challenges. Always perform a complete database backup before adjusting precision settings, and verify the changes with test calls before resuming normal operations. Contact us on WhatsApp: +8801911119966 for safe changeover procedures.

What happens if FEE_PRECISTION is lower than needed for my rates?

If SERVER_BILLING_FEE_PRECISTION is set too low for your actual rate requirements, VOS3000 will round or truncate your billing rates to fit the configured decimal places. For example, if you enter a rate of $0.0045 per minute with FEE_PRECISTION=2, the system stores it as $0.01 per minute — more than double the intended rate. This can cause massive billing overcharges to clients or unexpected revenue shortfalls when reconciling with vendor invoices. Always set FEE_PRECISTION high enough to accommodate your smallest rate increments.

How do FEE_PRECISTION and FEE_UNIT interact with billing modes?

VOS3000 fee decimal precision and fee unit work independently of the billing mode (per-minute, per-second, or per-block). The billing mode first determines the billable duration and calculates the raw fee using the rate, then FEE_PRECISTION controls the decimal places of the result, and finally FEE_UNIT rounds the fee to the specified minimum increment. This means all three layers — billing mode, precision, and rounding unit — must be configured in harmony for accurate billing. You can use VOS3000 monitoring tools to verify the combined effect on CDR records.

What precision do wholesale carriers typically use in VOS3000?

Most wholesale VoIP carriers configure SERVER_BILLING_FEE_PRECISTION to 3 (three decimal places, down to $0.001) and SERVER_BILLING_FEE_UNIT to 0.001. This combination provides sufficient granularity for typical wholesale rates while maintaining practical rounding boundaries. Carriers operating with ultra-thin margins on extremely high-volume routes may set FEE_PRECISTION to 4 and FEE_UNIT to 0.0001 for maximum precision. The key consideration is whether your vendor agreements specify rates that require more than 2 decimal places to represent accurately.

VOS3000 Billing Free Time Powerful Duration Shaving Configuration

April 19, 2026April 19, 2026 king

VOS3000 Billing Free Time Powerful Duration Shaving Configuration

Understanding VOS3000 billing free time is essential for carriers who want to run “first X seconds free” promotions or adjust call durations before billing calculation. The SERVER_BILLING_FREE_TIME parameter in VOS3000 subtracts a configurable number of seconds from every CDR duration, effectively offering callers a free window before metered billing begins. Need help configuring this on your switch? Reach out on WhatsApp: +8801911119966 for expert assistance.

This powerful feature, documented in §4.3.5.1 of the VOS3000 server manual, allows providers to shave off seconds from the recorded call duration before the billing engine applies rates. Whether you operate in per-minute or per-second billing mode, the free time deduction happens first, fundamentally changing how revenue is calculated on every single call.

How VOS3000 Billing Free Time Works

The SERVER_BILLING_FREE_TIME parameter defines how many seconds are subtracted from the raw CDR duration before any rate calculation occurs. For example, if a call lasts 66 seconds and SERVER_BILLING_FREE_TIME is set to 6, the billing engine sees only 60 seconds. This mechanism enables carriers to market “first 6 seconds free” promotions without creating complex rate tables.

📋 Parameter	📋 Value
Parameter Name	SERVER_BILLING_FREE_TIME
Manual Section	§4.3.5.1
Data Type	Integer (seconds)
Default Value	0 (disabled)
Scope	System-wide (all calls)
Effect	Subtracts X seconds from CDR duration before billing

VOS3000 Billing Free Time Calculation Examples

Let us examine how VOS3000 billing free time impacts real-world scenarios. The deduction is applied before the billing mode determines the billable units, so the interaction between free time and billing mode is critical to understand.

📋 Raw Duration	📋 Free Time (6s)	📋 Billed Duration (Per-Minute)	📋 Billed Duration (Per-Second)
5 seconds	6 seconds	0 minutes (no charge)	0 seconds (no charge)
12 seconds	6 seconds	1 minute	6 seconds
66 seconds	6 seconds	1 minute	60 seconds
125 seconds	6 seconds	2 minutes	119 seconds
366 seconds	6 seconds	6 minutes	360 seconds

Impact on Per-Minute vs Per-Second Billing Modes

The VOS3000 billing free time parameter interacts differently with per-minute and per-second billing modes. Under per-minute billing, the shaved duration is first reduced, then rounded up to the next full minute. Under per-second billing, the remaining seconds after deduction become the billable duration directly. This distinction can have significant revenue implications at scale.

📋 Billing Mode	📋 Free Time Effect	📋 Revenue Impact
Per-Minute (1/1)	Deduct then round up to full minute	High impact — short calls may become free
Per-Minute (60/60)	Deduct then round up to full minute	Moderate — same rounding after deduction
Per-Second (1/1)	Deduct exact seconds from duration	Precise — exact second-by-second deduction
Per-Second (6/6)	Deduct then round to 6-second blocks	Moderate — block rounding after deduction

Why Carriers Use VOS3000 Billing Free Time

Carriers deploy VOS3000 billing free time for several strategic reasons. The most common use case is promotional marketing — offering the “first 6 seconds free” attracts price-sensitive customers and differentiates your service in competitive wholesale markets. Beyond promotions, free time also compensates for call setup and post-dial delay, ensuring customers are not billed for time spent establishing the SIP session.

📋 Use Case	📋 Typical Free Time	📋 Reasoning
Promotional Campaign	6 seconds	“First 6 seconds free” marketing hook
Post-Dial Delay Compensation	3-5 seconds	Skip billing during call setup time
Short Call Filtering	10 seconds	Eliminate billing for failed/short calls
Competitive Wholesale Rate Matching	1-6 seconds	Match competitors’ effective rate structure
Ringing Time Exclusion	Varies	Do not charge for ringing before answer

Configuring SERVER_BILLING_FREE_TIME Step by Step

Setting up VOS3000 billing free time requires modifying the server billing parameters through the VOS3000 management interface. The parameter is system-wide, meaning it applies to all calls processed by the server. Navigate to System Settings → Billing Parameters → SERVER_BILLING_FREE_TIME and enter the desired number of seconds.

📋 Step	📋 Action	📋 Details
1	Log in to VOS3000 Admin Panel	Use admin credentials with billing config rights
2	Navigate to System Settings	Go to Billing Parameters section
3	Locate SERVER_BILLING_FREE_TIME	Find parameter under §4.3.5.1 settings
4	Set value in seconds	Enter integer value (e.g., 6 for 6 seconds free)
5	Save and restart billing service	Apply changes and restart the billing engine
6	Verify with test CDR	Make test call and check CDR for deducted duration

Revenue Impact Analysis with VOS3000 Billing Free Time

Understanding the revenue impact of VOS3000 billing free time is critical before enabling it system-wide. Even a small deduction of 6 seconds per call can reduce revenue by 5-10% on short-duration traffic. The table below shows estimated revenue changes based on average call duration and free time settings at a $0.01/minute rate.

📋 Avg Call Duration	📋 Free Time = 0s	📋 Free Time = 6s	📋 Revenue Loss
30 seconds	$0.01	$0.01 (24s → 1min)	0% (per-min rounding)
60 seconds	$0.01	$0.01 (54s → 1min)	0% (per-min rounding)
66 seconds	$0.02	$0.01 (60s → 1min)	50%
180 seconds	$0.03	$0.03 (174s → 3min)	0% (per-min rounding)

Common VOS3000 Billing Free Time Mistakes

Many administrators make preventable errors when configuring VOS3000 billing free time. The most dangerous mistake is setting free time too high for per-minute billing, which can eliminate revenue on short calls entirely. Another common error is forgetting that free time is system-wide and cannot be applied per-client or per-prefix without workarounds.

📋 Mistake	📋 Consequence	📋 Prevention
Setting free time too high (30s+)	Massive revenue loss on short calls	Keep below 10 seconds; test with sample CDRs
Not restarting billing service	Changes do not take effect	Always restart after config changes
Ignoring per-minute rounding interaction	Unexpected revenue drops	Model billing mode interaction before enabling
Applying to all traffic uniformly	Free time given where not intended	Monitor CDRs per client after enabling

Frequently Asked Questions About VOS3000 Billing Free Time

What is SERVER_BILLING_FREE_TIME in VOS3000?

SERVER_BILLING_FREE_TIME is a system-wide billing parameter in VOS3000 that subtracts a specified number of seconds from every CDR call duration before the billing engine calculates charges. When set to 6, for example, a 66-second call is billed as if it lasted only 60 seconds. This feature is commonly used by carriers to offer promotional “first X seconds free” deals or to compensate for post-dial delay and call setup time that should not be charged to the customer.

Does VOS3000 billing free time apply per client or per vendor?

No, the SERVER_BILLING_FREE_TIME parameter applies system-wide across all calls processed by the VOS3000 server. It cannot be configured individually per client, per vendor, or per prefix through this parameter alone. If you need different free time values for different clients, you would need to adjust your rate tables or use prefix-based billing strategies to achieve an equivalent effect. Always test configuration changes with sample calls before deploying to production.

How does free time interact with per-minute billing in VOS3000?

Under per-minute billing mode, VOS3000 billing free time is deducted from the raw CDR duration first, and then the remaining duration is rounded up to the next full minute for billing. This means a 66-second call with 6 seconds free time becomes 60 seconds, which rounds to exactly 1 minute. However, a 65-second call with 6 seconds free becomes 59 seconds, which still rounds up to 1 minute, resulting in the same charge as without free time in many cases.

Can I set different free time values for different routes?

The standard SERVER_BILLING_FREE_TIME parameter does not support per-route configuration since it is a global server setting. However, you can achieve similar results by creating separate rate plans with adjusted per-minute rates that effectively account for the free time, or by using prefix-based billing rules. For complex multi-route free time requirements, consult with a VOS3000 specialist who can design a billing architecture that meets your needs. Contact us on WhatsApp: +8801911119966 for help.

What happens if free time exceeds the call duration?

If the SERVER_BILLING_FREE_TIME value is greater than or equal to the actual CDR duration, the billed duration becomes zero, and the call is not charged at all. For example, a 5-second call with 6 seconds of free time results in a negative adjusted duration, which VOS3000 treats as zero billable time. This is why setting free time too high can be financially dangerous, especially on networks with a high percentage of short-duration calls under 30 seconds.

Is VOS3000 billing free time visible in CDR records?

The CDR record in VOS3000 typically shows the raw call duration, not the duration after free time deduction. The billing engine applies the free time subtraction internally during rate calculation. To verify that free time is working correctly, you must compare the raw CDR duration with the billed amount and confirm the math matches the expected deduction. Using the VOS3000 monitoring tools can help you track these discrepancies effectively.

How do I disable VOS3000 billing free time?

To disable VOS3000 billing free time, simply set the SERVER_BILLING_FREE_TIME parameter back to 0 (zero) in the system billing parameters. When the value is 0, no seconds are subtracted from CDR durations, and billing is calculated on the full raw duration of every call. After changing the value, you must restart the billing service for the change to take effect. Always verify by placing a test call and checking the resulting CDR and billed amount.

VOS3000 No-CDR Free Numbers Smart Zero-Record Configuration

April 19, 2026April 19, 2026 king

VOS3000 No-CDR Free Numbers Smart Zero-Record Configuration

Configuring VOS3000 no-CDR free numbers is a powerful optimization technique for VoIP operators who handle large volumes of free calls. The SERVER_BILLING_NO_CDR_E164S parameter goes beyond simple zero-charge billing — it eliminates CDR generation entirely for matching numbers, significantly reducing database write operations and storage requirements. Need expert guidance? Contact us on WhatsApp: +8801911119966.

Unlike the FREE_E164S parameter that still produces a zero-charge CDR record, NO_CDR_E164S ensures that calls to specified numbers leave no billing trace at all. This distinction is critical for high-volume environments where thousands of free calls per hour can unnecessarily bloat the CDR database and degrade system performance.

VOS3000 No-CDR Free Numbers Parameter Details

The SERVER_BILLING_NO_CDR_E164S parameter is defined in the VOS3000 server billing configuration, as documented in section §4.3.5.1 of the administration manual. It accepts a comma-separated list of E164 number patterns, using the same wildcard syntax as other billing parameters. When a call destination matches any pattern in this list, the billing engine skips CDR creation entirely.

📋 Property	📋 Value
Parameter Name	SERVER_BILLING_NO_CDR_E164S
Configuration File	mbx2008.conf or server billing config
Data Type	Comma-separated E164 patterns
Default Value	Empty (no numbers exempt from CDR)
Wildcard Support	Yes (asterisk * for prefix matching)
Manual Section	§4.3.5.1

NO_CDR_E164S vs FREE_E164S: Critical Differences

Understanding the distinction between these two VOS3000 billing parameters is fundamental. Both handle free calls, but their impact on the billing pipeline and database is completely different. This comparison is essential for any operator implementing VOS3000 no-CDR free numbers properly.

📋 Feature	📋 FREE_E164S	📋 NO_CDR_E164S
CDR Generated	Yes (zero-charge record)	No (no record at all)
Billing Amount	0.00	N/A (no record exists)
Database Write	Yes	No
Call Tracking	Full tracking available	No tracking from CDR
Rate Table Lookup	Skipped	Skipped
Audit Trail	Preserved	None
Performance Impact	Moderate (still writes CDR)	Minimal (skips write)

When to Use VOS3000 No-CDR Free Numbers

Choosing between FREE_E164S and NO_CDR_E164S depends on your business requirements for call tracking versus system performance. Our VOS3000 specialists can help you make the right choice — reach us on WhatsApp: +8801911119966. Here are the scenarios where skipping CDR generation makes the most sense.

📋 Scenario	📋 Recommended Parameter	📋 Reason
Emergency numbers (911, 112)	FREE_E164S	Audit trail required by regulation
High-volume test numbers	NO_CDR_E164S	No need for test call records
Internal PBX extensions	NO_CDR_E164S	On-net calls need no billing trace
Toll-free customer hotlines	FREE_E164S	Track call volume for capacity planning
Health-check probe numbers	NO_CDR_E164S	Frequent automated checks, no value in CDR
Regulatory-mandated free calls	FREE_E164S	Compliance requires call records

Configuration Steps for Zero-Record Setup

Setting up VOS3000 no-CDR free numbers follows the same configuration pattern as other billing parameters. Always create a backup before modifying your server configuration — our backup and restore guide walks you through the process.

📋 Step	📋 Action	📋 Command or Detail
1	Backup configuration	cp mbx2008.conf mbx2008.conf.bak
2	Edit configuration file	vi /etc/vos3000/mbx2008.conf
3	Add NO_CDR_E164S parameter	SERVER_BILLING_NO_CDR_E164S=5000,6000,7000
4	Save configuration	:wq in vi
5	Restart VOS3000 service	service vos3000 restart
6	Verify CDR absence	Test call then check CDR table — no record should exist

Database Performance Impact Analysis

The primary advantage of VOS3000 no-CDR free numbers is the reduction in database write operations. In high-volume VoIP environments where thousands of free calls occur hourly, eliminating unnecessary CDR inserts can dramatically improve MySQL performance. For more on monitoring your VOS3000 system health, see our VOS3000 monitoring guide.

📋 Metric	📋 Without NO_CDR	📋 With NO_CDR
CDR Inserts per Hour (10K free calls)	10,000	0
MySQL Disk I/O	High	Reduced proportionally
CDR Table Size Growth	Rapid	Slower
Query Performance	Degrades over time	More stable
Backup Size	Larger	Smaller
Billing Engine CPU Load	Higher (CDR write overhead)	Lower (skipped writes)

Wildcard Pattern Configuration Examples

The wildcard matching for VOS3000 no-CDR free numbers works identically to other billing parameters. The asterisk character matches any number of trailing digits, enabling efficient coverage of entire number ranges without listing each number individually.

📋 Pattern	📋 What It Matches	📋 Typical Use Case
5000*	All numbers starting with 5000	Internal test range
6000*	All numbers starting with 6000	PBX extension range
7000	Exact number 7000 only	Specific health-check number
8800*	All numbers starting with 8800	Automated probe range
9999*	All numbers starting with 9999	Internal service codes

Best Practices for Zero-Record Configuration

Implementing VOS3000 no-CDR free numbers requires careful planning to balance performance gains with operational visibility. Never use NO_CDR_E164S for numbers where you need any form of audit trail, dispute resolution capability, or regulatory reporting. Always pair it with proper monitoring to ensure the configuration remains correct over time.

📋 Best Practice	📋 Description
Reserve for truly disposable calls	Only skip CDR for calls with zero reporting value
Use specific wildcard patterns	Avoid overly broad patterns like 1* that could match billable numbers
Document all NO_CDR entries	Maintain a separate record of which numbers skip CDR and why
Review configuration quarterly	Ensure patterns still match intended numbers only
Test after every change	Verify CDR is properly skipped and billable calls still generate records
Keep emergency numbers on FREE_E164S	Emergency calls need an audit trail even if they are free

Frequently Asked Questions About VOS3000 No-CDR Free Numbers

What is SERVER_BILLING_NO_CDR_E164S in VOS3000?

SERVER_BILLING_NO_CDR_E164S is a VOS3000 server billing parameter that specifies E164 numbers or wildcard patterns for which CDR records should not be generated at all. When a called number matches any pattern in this list, the billing engine completely skips the CDR write operation, resulting in zero database record creation for that call. This differs from FREE_E164S which still creates a zero-charge CDR, making NO_CDR_E164S ideal for high-volume free-call scenarios where no audit trail is needed.

How is NO_CDR_E164S different from FREE_E164S?

The key difference is that FREE_E164S still generates a CDR record with a zero billing amount, while NO_CDR_E164S skips CDR generation entirely. With FREE_E164S, you retain a complete call audit trail showing that the call occurred with no charge. With NO_CDR_E164S, there is no record whatsoever — the call is invisible in CDR-based reports. Use FREE_E164S when you need tracking and compliance, and NO_CDR_E164S when you need maximum database performance for truly disposable calls.

When should I use VOS3000 no-CDR free numbers instead of zero-charge billing?

You should use VOS3000 no-CDR free numbers when the calls have zero reporting or audit value and are generated in high volumes that could impact database performance. Common examples include automated health-check probes, internal PBX extension calls, route testing numbers, and any repetitive system-generated calls where keeping records provides no business benefit. If regulatory compliance requires call tracking, or if you need dispute resolution data, use FREE_E164S instead to maintain the zero-charge CDR record.

Can I use both NO_CDR_E164S and FREE_E164S simultaneously?

Yes, you can configure both SERVER_BILLING_NO_CDR_E164S and SERVER_BILLING_FREE_E164S on the same VOS3000 server. They serve complementary purposes — FREE_E164S for numbers that need tracking with zero charges, and NO_CDR_E164S for numbers that should generate no record at all. However, you should avoid listing the same number in both parameters, as this could create ambiguous behavior. If a number appears in both lists, NO_CDR_E164S typically takes precedence, but it is best practice to ensure no overlap between the two lists.

How do I verify that CDR generation is being skipped?

To verify that VOS3000 no-CDR free numbers configuration is working correctly, place a test call to a number that matches your NO_CDR_E164S pattern, then query the CDR table in MySQL. You should find no record of that call at all. Compare this with a call to a normal billable number which should produce a CDR entry. You can use the VOS3000 CDR portal or direct MySQL queries to confirm. Refer to our VOS3000 CDR analysis and billing guide for help interpreting CDR records.

Does skipping CDR affect call routing or quality?

No, the SERVER_BILLING_NO_CDR_E164S parameter only affects the billing and CDR generation stage of call processing. It has no impact on call routing decisions, SIP signaling, codec negotiation, or audio quality. The call is routed and processed normally through the VOS3000 softswitch — the only difference is that the billing engine does not create a database record after the call completes. The call setup, media handling, and teardown processes remain completely unaffected by this configuration.

What happens if I accidentally add a billable number to NO_CDR_E164S?

If you add a billable number to the NO_CDR_E164S list, calls to that number will not generate any CDR record, meaning you will lose all billing data for those calls. This can result in revenue leakage because there will be no record to bill against. This is why it is critical to use specific wildcard patterns rather than overly broad ones, document all entries, and review the configuration regularly. Always test with a small pattern first and verify that only intended numbers are affected before deploying broadly.

VOS3000 Billing Time Precision Essential Hold Time Rounding Easy Configuration

April 19, 2026April 19, 2026 king

VOS3000 Billing Time Precision Essential Hold Time Rounding Configuration

Understanding VOS3000 billing time precision is critical for every VoIP operator who wants accurate call duration measurement and fair customer billing. The SERVER_BILLING_HOLD_TIME_PRECISION parameter controls how the system rounds call hold times in milliseconds, directly impacting your revenue and client invoices. Need help configuring this setting? Contact us on WhatsApp: +8801911119966 for expert assistance.

When a SIP call terminates, VOS3000 records the exact duration in milliseconds. However, billing calculations require a rounding decision. The hold time precision parameter defines the rounding threshold that converts fractional seconds into billable whole seconds, making it one of the most important revenue-affecting configurations in your system.

How VOS3000 Billing Time Precision Works

The SERVER_BILLING_HOLD_TIME_PRECISION parameter (documented in manual section §4.3.5.1) sets the millisecond threshold for rounding call duration upward. When the fractional portion of a call’s duration meets or exceeds this threshold, the system rounds up to the next whole second. When it falls below the threshold, the system truncates the fractional portion and rounds down.

📋 Parameter	📋 Detail
Parameter Name	SERVER_BILLING_HOLD_TIME_PRECISION
Section	§4.3.5.1 Server Billing Parameters
Default Value	50 (milliseconds)
Value Range	0-999 milliseconds
Effect	Sets rounding threshold for call duration billing

The 50ms Rounding Threshold Explained

With the default threshold of 50 milliseconds, VOS3000 billing time precision follows a simple but powerful rule: any call duration whose fractional millisecond portion is 50ms or greater gets rounded up, while anything below 50ms gets rounded down. This is the standard midpoint rounding approach used in telecom billing worldwide.

📋 Raw Duration	📋 Fractional ms	📋 vs 50ms Threshold	📋 Billed Duration
21.049s	49ms	Below 50ms	21 seconds
21.050s	50ms	Meets 50ms	22 seconds
21.001s	1ms	Below 50ms	21 seconds
21.999s	999ms	Above 50ms	22 seconds
21.500s	500ms	Above 50ms	22 seconds

Revenue Impact of VOS3000 Billing Time Precision

Even a single second of rounding difference across millions of calls creates significant revenue shifts. Let us examine the financial implications of different threshold values on a sample traffic volume. For personalized revenue analysis, reach out on WhatsApp: +8801911119966.

📋 Threshold Setting	📋 Rounding Behavior	📋 Revenue Direction	📋 Best Use Case
0ms	Always round up	Maximum revenue	Aggressive wholesale billing
50ms (default)	Midpoint rounding	Balanced	Standard fair billing
500ms	Round up only above half	Slightly reduced	Competitive pricing advantage
999ms	Almost always truncate	Minimum revenue	Customer-friendly rounding

Configuring SERVER_BILLING_HOLD_TIME_PRECISION

To modify VOS3000 billing time precision, navigate to the server billing parameters in the VOS3000 administrative interface. The parameter is located under the system configuration section. After changing the value, you must restart the billing service for the new threshold to take effect on subsequent calls.

📋 Step	📋 Action	📋 Notes
1	Log in to VOS3000 admin panel	Use administrator credentials
2	Navigate to System Settings > Server Parameters	Section §4.3.5.1
3	Locate SERVER_BILLING_HOLD_TIME_PRECISION	Default is 50
4	Enter new threshold value (0-999)	Consider revenue impact first
5	Save and restart billing service	Changes apply to new calls only

Revenue Calculation Examples

Consider a wholesale route billing at $0.01 per minute with 1 million calls per day. A single-second rounding difference per call translates to substantial monthly revenue variation. The table below illustrates the annualized impact of VOS3000 billing time precision settings on your bottom line.

📋 Scenario	📋 Calls/Day	📋 Avg Extra Secs/Call	📋 Monthly Revenue Impact
Threshold 0ms vs 50ms	1,000,000	+0.49s average	+$2,450 approx.
Threshold 50ms vs 500ms	1,000,000	+0.22s average	+$1,100 approx.
Threshold 0ms vs 999ms	1,000,000	+0.50s average	+$2,500 approx.

Best Practices for Hold Time Precision Settings

Choosing the right VOS3000 billing time precision threshold depends on your business model and client relationships. Wholesale operators serving other carriers often prefer the default 50ms for fairness, while retail providers may lean toward 0ms for maximum billable duration. Always document your rounding policy in client agreements to avoid disputes.

📋 Best Practice	📋 Recommendation	📋 Reason
Default setting	Keep at 50ms	Industry-standard midpoint rounding
Client transparency	Document rounding in SLAs	Prevents billing disputes
A/B testing	Compare CDRs before changing	Quantifies actual impact
Regulatory compliance	Check local telecom regulations	Some jurisdictions mandate rounding rules
Backup before changes	Export current configuration	Enables quick rollback

Rounding Impact on CDR Records

When VOS3000 billing time precision rounds a call duration, the CDR record reflects the rounded value. This means the stored billable duration in the CDR may differ from the actual measured duration by up to nearly one full second. Understanding this discrepancy is essential for CDR reconciliation and audit processes.

📋 CDR Field	📋 Description	📋 Affected by Rounding
Call Duration	Billed duration in seconds	Yes — rounded per threshold
Start Time	Call establishment timestamp	No
End Time	Call termination timestamp	No
Billing Amount	Calculated charge	Yes — derived from rounded duration

Frequently Asked Questions About VOS3000 Billing Time Precision

What is SERVER_BILLING_HOLD_TIME_PRECISION in VOS3000?

SERVER_BILLING_HOLD_TIME_PRECISION is a server-side billing parameter in VOS3000 that defines the millisecond threshold used for rounding call durations. When the fractional millisecond portion of a call’s duration meets or exceeds this threshold value, the system rounds the duration up to the next whole second. When the fractional portion falls below the threshold, the system truncates it and rounds down. The default value is 50 milliseconds, which implements standard midpoint rounding behavior.

Why does 21.049s bill as 21 seconds but 21.050s bills as 22 seconds?

With the default SERVER_BILLING_HOLD_TIME_PRECISION value of 50 milliseconds, the system checks the fractional portion of the call duration against the 50ms threshold. A call lasting 21.049 seconds has a fractional portion of 49 milliseconds, which is below the 50ms threshold, so the system truncates it and bills for 21 seconds. A call lasting 21.050 seconds has a fractional portion of exactly 50 milliseconds, which meets the threshold, so the system rounds up and bills for 22 seconds. This single millisecond difference results in a one-second billing difference.

How does VOS3000 billing time precision affect my revenue?

VOS3000 billing time precision directly impacts revenue by controlling whether fractional seconds are rounded up or down on every single call. On high-traffic routes processing millions of calls daily, even a fraction of a second per call accumulates into significant revenue variations. Setting the threshold to 0ms ensures every fractional second rounds up, maximizing billable duration and revenue. Setting it to 999ms essentially truncates nearly all fractional seconds, reducing billable time but potentially making your rates more attractive to price-sensitive clients.

Can I set the hold time precision to always round up?

Yes, you can set SERVER_BILLING_HOLD_TIME_PRECISION to 0 milliseconds to ensure that all call durations with any fractional second component are rounded up to the next whole second. This means a call of 21.001 seconds would bill as 22 seconds. This configuration maximizes your billable duration and is commonly used by wholesale operators who want to capture every possible second of revenue. However, you should clearly communicate this rounding policy to your clients to maintain trust and avoid billing disputes.

Do I need to restart VOS3000 after changing the precision setting?

Yes, after modifying the SERVER_BILLING_HOLD_TIME_PRECISION parameter, you must restart the VOS3000 billing service for the new threshold value to take effect. The change applies only to new calls established after the restart. Existing calls and already-generated CDR records are not retroactively adjusted. It is strongly recommended to schedule this restart during a low-traffic maintenance window and to back up your current configuration beforehand using the procedures described in our backup guide.

Is the 50ms default threshold compliant with telecom regulations?

The 50ms default threshold implements standard midpoint rounding, which is widely accepted in telecom billing practices and aligns with general commercial rounding conventions. However, telecom billing regulations vary by jurisdiction. Some countries or regulatory bodies may mandate specific rounding behaviors for VoIP or telecommunication services. You should consult with a local telecom compliance expert or legal advisor to confirm that your chosen VOS3000 billing time precision setting meets all applicable regulatory requirements in your operating regions. For guidance, contact us on WhatsApp: +8801911119966.

What happens if I set the threshold to 999 milliseconds?

Setting SERVER_BILLING_HOLD_TIME_PRECISION to 999 milliseconds means that only calls with a fractional portion of 999 milliseconds (effectively a full additional second) will be rounded up. In practice, this means almost all calls will have their fractional seconds truncated, and the billed duration will match the whole-second floor of the actual duration. This is the most customer-friendly rounding option, as it minimizes the billable duration. However, it also reduces your revenue compared to lower threshold values, so careful financial analysis is recommended before making this change.

🔍 What is VOS3000 Parameter Description

Reference: VOS3000 2.1.9.07 Manual, Section 4.3.5 (Pages 222-252)

The VOS3000 parameter description framework organizes all configuration settings into a hierarchical structure that reflects the functional architecture of the softswitch system.

❓ Frequently Asked Questions about VOS3000 Parameter Description

What is the most important VOS3000 parameter description for billing accuracy?

The SERVER_BILLING_FEE_PRECISION and SERVER_BILLING_FEE_UNIT parameters are critical for billing accuracy. These parameters control the decimal precision and billing unit for charge calculations. Configure these parameters according to your business requirements and regulatory requirements for billing precision.

How do I enable NAT keep-alive in VOS3000 parameter description?

To enable NAT keep-alive, set SS_SIP_NAT_KEEP_ALIVE_MESSAGE to a non-empty value (default is “HELLO”). If this parameter is empty, NAT keep-alive is disabled. Configure SS_SIP_NAT_KEEP_ALIVE_PERIOD to control the interval between keep-alive transmissions (default is 30 seconds).

What happens if I set SS_SIP_SESSION_TTL too low?

Setting SS_SIP_SESSION_TTL too low (below 90 seconds) may cause frequent session refresh messages, increasing network traffic and potentially causing call quality issues. The minimum recommended value is 90 seconds as specified in RFC 4028. Values below this may trigger “422 Session Interval Too Small” errors from endpoints.

How do I disable automatic report generation?

To disable automatic generation of specific reports, set the corresponding SERVER_REPORT_ parameter to “Off” in the System Parameter interface. For example, to disable the Agent Income Report, set SERVER_REPORT_AGENT_INCOME to “Off”. Disabled reports can still be generated manually through the client interface.

Can I use VOS3000 parameter description to limit maximum call duration?

Yes, use the SS_MAX_CALL_DURATION parameter to limit the maximum call duration for all calls. Set the value in seconds (0 means unlimited). This parameter is useful for preventing runaway calls and controlling costs. Individual accounts may have additional duration limits configured in their settings.
